ALUMNI
Ishani Singh
Post-graduate Adventures
Ishani was an undergraduate student in the Greco lab from 2020 to 2024.

Dennis May
Field Applications Scientist, IsoPlex, USA
Denny was a PhD student in the Greco lab from 2018 to 2023.

Sangwon Yun
MD Candidate, Yale, USA
Sangwon was a PhD student in the Greco Lab from 2019 to 2023. Initially he studied the interplay between b-catenin mutant stem cells and their wild type neighbors in the epidermis before switching directions to work with Dennis May. Together they explored a novel quantitative pipeline that revealed how stem cell chromatin compaction changes through differentiation along with a cells transcriptional state.
Katherine Cockburn
Assistant Professor Department, McGill, Canada
Katie was a Postdoctoral Fellow in the Greco Lab from 2015 to 2022. She utilized frequent revisits in her imaging to follow individual stem cell fates over days in murine skin. In combination with complex mathematically modeling she expanded our understanding of how epidermal stem cells orchestrate and balance self-renewal and differentiation to maintain homeostasis in adult murine skin.

Karen was an undergraduate/graduate student at Yale while in the Greco lab from 2018 to 2021. She worked primarily on better understanding the relationship between homeostasis and cancer, contributing to projects by Cristiana Pineda, Sara Gallini and Anupama Hemalatha throughout her tenure. She is now continuing her studies at Oxford University pursuing a Master’s Degree in Global Health Science & Epidemiology.
Sangbum Park
Assistant Professor, MSU, USA
Sangbum was a Postdoctoral Fellow in the Greco Lab from 2013 to 2019 and established our experimental approach to study epidermal stem cells in the skin during wound healing through intravital imaging. He discovered that highly proliferative stem cells directionally divide towards the wound while migrating with differentiated cells, both of which functionally participate in the wound repair process.
Edward Marsh
Postdoctoral Associate, Yale, USA
Edward was a PhD student in the Greco Lab from 2015 to 2019 and was the first to apply our techniques of intravital imaging of epithelial cells to the dermal fibroblast population. He discovered that mammalian fibroblasts remain in a stable position over the lifetime of the individual and, when lost, are not replaced during aging. Instead, dynamic fibroblast membrane projections extend to fill spaces created from lost neighboring fibroblasts.
Jonathan Boucher
PhD Candidate, Northwestern University, USA
Jonathan was a research assistant in the Greco Lab from 2014 to 2018 and while his primary efforts were to ensure the lab constantly functioned smoothly, he also simultaneously contributed to multiple projects throughout his tenure.

MD Candidate, Georgetown University, USA
Cristiana was a PhD student in the Greco Lab from 2014 to 2018 and focused her efforts on studying mutant clones within the adult murine epidermis. Expanding on her work studying beta-catenin mutants with Samara Brown, she discovered that Hras mutant cells in the hair follicle drive enhanced homeostatic mechanisms that act to suppress oncogenic growth by integrating the mutant cells into the tissue.
